ABSTRACT:
A safety system for use with apparatus having a conductive member and where the apparatus changes the attitude and/or altitude of the conductive member during its operation includes at least one sensor which senses an electric field and provides a signal representative of the strength of the electric field. A safety device responsive to the signal from the sensor prevents the further changing of the conductive member's attitude and/or altitude when the electric field strength is greater than a predetermined safe value.
